SOD123F Rectifiers
SOD123F High-Voltage Rectifiers Enable Compact
Dimensions for Portable Products
Diodes Incorporated announces the
introduction of a glass-passivated
rectifier series which is housed in the
low-profile and small form-factor
“SOD123F” package. The state-of-theart small package technology enables
very compact dimensions for portable
products which adopt this series of
rectifier devices.
The rectifier series is comprised of two
rectifier devices, each exhibiting high
reverse breakdown voltage (VRRM
≥1000V) and high forward-current surge
capability (IFSM ≥30A). The glass
passivated die construction ensures
robust performance and high reliability.
The initial release of the rectifier series
includes the S1MWF which is a
standard rectifier device, and the
RS1MWF which is a fast-recovery
rectifier device. Both are well suitable
for power supply and adapter
applications.
The fast switching frequency and the
low reverse-recovery time of the
RS1MWF reduce the switching loss and
increase the power conversion
efficiency of the power supply in which
the device is applied. Either of these
devices can be used in a full-wave
bridge configuration for AC-to-DC
rectification from the main AC supply.
Delivering superior performance, these
devices are ideally suited for today’s
high-speed fully-automated assembly
processes.
The SOD123F package is fully green
and RoHS-compliant. (See diodes.com
for further details).
The Diodes’ Advantage
 Low-Profile Package, Small Form-Factor Package
The low profile (1.15mm maximum) and small form factor of the SOD123F
package (3.5mm x 1.8mm typical) enable lower z-height of the adopting portable
products.
 Low Reverse Leakage Current
The devices have low reverse leakage current (IR<5uA @ VR=1,000V) which
improves the efficiency of the rectifier during both reverse-mode and switchmode operation.
 High Forward Surge Current Capability
The clip die-attach structure used in the assembly of the devices enable them to
withstand high surge currents (up to 30A), resulting in improved reliability and
product lifetime.
 Fast Switching Speed for High Power Efficiency
The fast switching speed of the RS1MWF reduces switching loss and increases
power efficiency. It is ideally suited for applications like switched-mode power
supplies, PFC (power factor correction) and other fast switching applications.
